National Dairy Month: Share the story of dairy’s essential role in nourishing the world

It's national Dairy Month. What would a world without cows look like? It would be harder to nourish the world.

World Milk Day, June 1, kicked off National Dairy Month in the U.S. To celebrate, we are exploring the cultural, economic, nutritional and environmental impact of dairy — and why it matters to the future of food. Whether hand-milked in smallholder farms or harvested in robotic dairies, milk provides vital nutrients to billions, supporting millions of farmers in the process. 

Together, we’re asking: What would we lose in a world without milk? The global dairy industry goes far beyond the glass — it provides critical nutrition, supports the livelihoods of millions of families and drives innovation, playing a vital role in food security and the future of sustainable agriculture. By sharing your perspective, you contribute to a global conversation about the real value of dairy, and the vital role cows play in our diets, economies and cultures.

Join us in stirring up a global conversation about the essential role of dairy and the cows behind it.

We want you to be part of the conversation.

Fast facts

What happens to the global economy without dairy?

With a market projected to exceed $1 trillion by 2033, dairy is one of the world’s most powerful economic drivers. More than 110 million farmers worldwide directly benefit from dairy farming, while over 6 billion people rely on nutrient-rich milk and dairy foods — making dairy essential to both livelihoods and global nutrition.

How Dairy Nutrients Support Brain Health and Mood Regulation

Nutritional and Economic Impact: Essential Dairy Facts

Dairy farming supports over 110 million livelihoods globally and supplies essential micronutrients to 6 billion people, serving as a pillar of both public health and economic stability.

Global Economic Footprint and Livelihoods

The global dairy market is projected to exceed $1 trillion by 2033. Beyond its market size, dairy farming is a critical driver of rural economies:

  • 110M+ Dairy Farmers: Millions of smallholders and commercial producers directly rely on milk production for their income.

  • 6 Billion Consumers: Dairy products remain an indispensable, cost-effective source of high-quality protein and essential minerals worldwide.

Dairy Nutrients and Cognitive Function: The B12 and Mood Connection

Milk delivers a unique blend of vitamin B12, tryptophan, calcium, and potassium that supports central nervous system function, neurotransmitter synthesis, and emotional regulation.

While dairy is widely recognized for bone health, recent metabolic research highlights its role in brain function:

  • Neurotransmitter Synthesis: Vitamin B12 found in milk is essential for producing serotonin, dopamine, and norepinephrine—neurotransmitters that regulate mood, focus, and emotional stability.

  • Precursor for Serotonin: Dairy contains tryptophan, an essential amino acid that serves as a building block for mood-regulating pathways in the brain.

  • Reducing Deficiency Risks: Vitamin B12 deficiency is linked to cognitive decline and mood disorders, making daily dietary intake vital for mental well-being

The importance of a balanced diet

Milk and dairy products provide essential nutrients like calcium, potassium, vitamin D and high-quality protein. These support bone health, muscle function and cognitive development — especially in children, adolescents and expecting mothers.
